Section Four - S Registers
Your modem has 29 registers, designated S0 through
S28. Table 4-1 shows the registers, their functions, and their
default values. Some registers can have their values changed
by commands. If you use a command to change a register
value, the command remains in effect until you turn off or
reset your modem. Your modem then reverts to the operating
characteristics specified in its non-volatile memory. Refer to
Section 3 for information on how to use the AT commands to
manipulate the S registers.
